Abstract: ABSTRACT:          "Arrangement for checking the parity of parity bit-con-taining bit groups."           In a system in which the parity of many bit groups must be checked it is proposed to check these bit groups simultaneously and jointly. The parity bits generated by the parity generators are interchanged cross-wise, are combined with the parity bits contained in the bit groups and applied to a common output. Consequently, only this specific output must be checked. The checking circuit itself is checked by inverting one of the parity generators periodically.

Abstract: "TREATMENT OF PRIMARY TAILINGS AND MIDDLINGS   FROM THE HOT WATER EXTRACTION PROCESS FOR    RECOVERING BITUMEN FROM TAR SAND"            ABSTRACT OF THE DISCLOSURE The primary tailings and middlings are combined and fed to a vessel having the general form of a deep cone thickener.  The feed is deflected outwardly and generally horizontally by a baffle, as it is delivered to the vessel.  Simultaneously, the outwardly radiating layer of newly added feed is contacted from below by an upwelling stream of aerated middlings, which stream moves in parallel with the aforesaid layer.  Bitumen froth is formed and recovered.  The upwelling stream is provided by circulating middlings through eductor/aerator assemblies and a plenum chamber mounted centrally in the body of middlings in the vessel.  A generally circular circulation of middlings is generated. In this manner, the newly added bitumen is quickly and efficiently recovered.  Recirculation of middlings to the aeration zone yields an additional recovery of bitumen.  Use of the deep cone ensures that the tailings from the vessel are relatively low in water and bitumen content.

Abstract: VACUUM-TAMPER INDICATING BUTTON FOR SMALLER DIAMETER      CAPS AND THE LIKE ABSTRACT OF THE DISCLOSURE This relates to a closure cap for containers wherein the end wall of the closure cap and more particularly an end panel thereof may be subjected to a vacuum which will determine the condition within the container.  The closure cap involved is of a small diameter and is specifically intended for use in conjunction with neck finishes having diameters ranging from 27mm to 43mm.  The end panel of the closure cap is of a specific configuration so that a small diameter central portion in the form of a button will evert under the existing vacuum conditions so as to present a substantially plain end panel when the vacuum condition exists within the container and which will show a popped up button when the vacuum has been relieved.  The button will be indicative of product condition or possible tamper-ing.

Abstract: ABSTRACT           A symmetric finite impulse response filter for receiving a digital input signal and generating a filtered analog output signal for application to a balanced line, such as a tip and ring lead pair. Logic levels of predetermined symmetrical bit pairs of the digital input signal are detected and in response, predetermined corresponding capacitors are selectively switched between bias and reference voltages, thereby charging predetermined voltages proportional to the capacitances of the capacitors.  The predetermined voltages are summed in an operational amplifier which, in response produces a filtered analog output signal. Individual capacitors are utilized for realizing each pair of symmetrical coefficients of the filter transfer function, resulting in considerable economy of size.  A switched capacitor implementation results in high speed performance, simple design and low cost.

Abstract: ABSTRACT OF THE DISCLOSURE    An improved trunnion lubricant retainer for a univer-sal joint is provided.  A cross of a universal joint has four trunnions extending along two mutually perpendicular lines.  Bearing cups are rotatably received on the trun-nions and the cups are held by universal joint yokes.  Lu-brication passages extend from a central portion of the cross to cavities in the ends of the trunnions.  When the universal joint is stationary, lubricant such as grease could drain from an upper cavity downwardly, leaving the bearing cup of the upper trunnion devoid of lubricant when the universal joint is again operated.  An improved lubri-cant retainer now extends from an end of each passage through a substantial portion of the corresponding cavity and traps lubricant in an annular space between the cavity wall and the retainer so that this lubricant is readily available to lubricate the corresponding cup at all times.  The im-proved retainer is symmetrical about a central plane per-pendicular to its axis so that the retainer can be auto-matically assembled properly and its manufacture is sim-plified.

Abstract: TITLE: MASS ANALYZER SYSTEM WITH REDUCED DRIFT     ABSTRACT OF THE DISCLOSURE           A mass analyzer in which an ion signal, typi-cally from a plasma,  travels through an orifice into a vacuum chamber,  and  through a  focussing  system in  the vacuum chamber into a mass spectrometer and ion detect-or.  Drift of the detected ion signal, and differences in drift of the detected ion signal for different elements, are greatly reduced by a small shadow stop placed in the vacuum  chamber  immediately  behind  the  orifice.    The shadow stop and plate containing  the orifice are both preferably grounded.   The  focussing  system  includes  a Bessel box lens, and drift is further reduced by insu-lating the stop in the Bessel box lens from the barrel and biasing the Bessel stop differently from the barrel.

Abstract: ABSTRACT OF THE DISCLOSURE         An inverter using gate turn-off thyristors (GTOs) is controlled by means of pulse width modulation (PWM) to control the speed of an induction motor.  If the current flowing through the induction motor becomes an overcurrent which can still be cut off by the GTOs, a gate off signal is supplied to respective GTOs to interrupt the overcurrent.  If any one of arms re-spectively corresponding to phases is short-circuited, a gate on signal is supplied to all GTOs to distribute the short circuit current among the arms, and the main circuit is interrupted by a high-speed breaker.  At this time, a simultaneous gate on signal is given priority.  If the simultaneous gate on signal is present, a simultaneous gate off signal is disabled.  Owing to this configuration, destruction of the GTOs due to consecutive guard operation can be prevented.

Each friction assembly comprises a body of friction material engaging one of the two parallel surfaces, and a compression spring that urges the body of friction material against that surface.  The body of friction mate-rial and the spring are maintained captive between the lever arm and the surface of the frame that is engaged by the body of friction material.

Abstract: ABSTRACT            A method for use in an expert system which selectively allows the system to avoid asking the user a question by providing the answer to that question based on related information that may have been previously attained in the system.  The method involves providing an action attribute that can be attached to any node in the rule tree.  The attribute is assigned to a node in the tree which provides an answer to a class question based on processing various other dependent nodes.  When the answer is obtained, the action attribute then causes all other Dodes in she rule base referencing the same class question to be set to the same answer.  The user is therefore only requested to supply information as a last resort.
